Description

Technical Field

[0001] This invention relates to the fields of foundation pit engineering, underground construction engineering, geotechnical engineering, and disaster prevention engineering, and in particular to a soil anchor compaction device for caissons. Background Technology

[0002] Currently, caisson construction is increasingly being used in China for small vertical shafts and foundation pits. Existing caisson construction projects largely employ wet caissons without dewatering and prefabricated caissons. However, these actively controlled caissons primarily rely on ground assembly and pressurization for sinking. Because the pressurization point is above ground, it's difficult to control the caisson's sinking path, leading to the risk of serpentine or tilted caissons. Uneven settlement and other problems are difficult to remedy once they occur, resulting in serious consequences. Therefore, a caisson compaction device is needed to stabilize the caisson. Summary of the Invention

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.
